Specification of Letters Patent.

Patented Nov. 28, 1916.

To all whom it may concern."

Be it known that I, 'Innononn PIAZZE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Rudder-s; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in rudders.

The object of the present invention is to improve the construction of rudders for ships, more especially the manner of mounting the rudder in a ship and to provide a simple, practical and inexpensive construction adapted to enable a rudder in event of breakage at sea to be readily replaced by a new rudder in a comparatively short time and without danger thereby obviating the necessity of towing vessels having broken rudders and avoiding the payment of salvage.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing, Figure 1 is a sectional view of the stern portion of a vessel provided with a rudder constructed in accordance with this invention, Fig. 2 is a detail invention, 1 designates a rudder having its stock or pivot 2 extending through and journaled in a circular bearing portion 4 of a rudder case 5 constructed of suitable metal and designed to extend from the hull to the deck as clearly illustrated in Fig. l of the drawing. The rudder case 5 is provided. with a substantially key hole opening consisting of a circular portion 6 and a relatively narrow portion 7 extending rearwardly from the circular bearing opening 6 and adapted to permit the blade or body portion of the rudder 1 to be passed through it whereby a rudder may be easily and quickly shipped at seawithout danger. The rudder case is provided with a lower marginal attaching flange 8 extending outwardly from the rudder case and preferably arranged to conform to the configuration of the hull. as shown and secured to the same by suitable fastening devices. The rudder case is also provided at the top with a horizontal outwardly extending marginal attaching flange 9 arranged upon the deck 10 and secured to the same by suitable fastening devices 11 which also securea sectional. cap 12 to the top of the rudder case.

The sectional cap 12 is composed of. two longitudinal sections 13 fitted together over the narrow longitudinal portion 7 of the rudder case to close the sane at the said narrow portion 7 of the opening and provided with curved approximately se1ni-circular portions 1% fitting around the rudder stock and arranged upon the circular bearing portion of the casing and having terminal attaching portions 15 projecting beyond the casing as shown and secured to gether by transverse fastening devices 16. The relatively straight portions of the sections of the cap are provided at their inner longitudinal edges with upwardly extend ing longitudinal flanges 17 which are secured together by suitable fastening devices 18. By this construction, the sectional cap of the casing 5 is securely bolted together and also to the case which is provided at the top of the circular bearing portion with a recess 19 forming a seat for a collar 20 of the-stock of the rudder.

The collar is suitably secured to the stock of the rudder and it supports the same in proper position. The sections of the cap are also provided with plug sections 21 conforming to the configuration of the adjacent portions of the walls of the narrow portion 7 of the opening of the rudder case and adapted to aiford an eflicient closure of the same at the said narrow portion 7 of the opening. Any suitable packing may of course be employed to render the rudder case perfectly water tight and to prevent any leakage.

The rudder stock is provided at the top with an eye or ring 22 to enable the rudder to be readily hoisted in or out as required and the stock is provided at a point intermediate of the eye or ring in the collar with an aperture 22* for a steering bar 23 and to be connected with the ropes or cables of the steering gear but the latter may be connected with the stock o1 the rudder in any other desired manner. The tiller bar or steering bar is provided at its ends with openings 24 for the attachment of the said ropes or cables.

What is claimed is 1. The combination with a ship or the like having an elongated opening therein, of a rudder, a rudder case arranged vertically in said opening and designed to extend from the bottom of the hull upwardly and provided with upper and lower marginal attaching portions, said casing having a substantially circular bearing opening to receive the stock or pivot of the rudder and provided also with a relatively narrow extension to form a casing for the body or blade of the rudder, and a cap secured to the top of the casing and fitting around the stock or pivot of the rudder forming a liquid tight joint.

2. The combination with a ship or the like having an elongated opening therein,

of a rudder, a rudder case having a substantially circular bearing opening and provided with a relatively narrow extension opening, said rudder adapted to pass through the rudder case, and having a stock or pivot j ournaled in the circular opening, and a cap secured to the rudder case and having a plug fitting in and filling the extension opening to close the same at the top of the case, forming a liquid tight joint.

3. The combination with a ship or the like having an opening therein, of a rudder, a rudder case having a circular bearing opening and provided at the top thereof with a recess forming a seat, said casing being also provided with a relatively narrow extension opening, said rudder adapted to pass through the rudder case and having a stock or pivot provided with a collar arranged in said recess and a sectional cap tted on the rudder case and extending around the stock or pivot forming a liquid tight joint.

4. The combination with a ship or the like having an opening therein, of a rudder case seated in said opening, and secured to the deck and hull thereof, said case comprising a substantially circular portion and an oblong extension, a rudder adapted to pass through the rudder case and having a stock or pivot arranged in the circular portion of case, and a sectional cap composed of longitudinal sections provided with a plug fitted in the oblong portion of the rudder case, said sections being also provided with approximately semi-circular portions fitting around the stock or pivot of the rudder and having a terminal attaching means forming a liquid tight connection with the case.

In testimony whereof I affix my signature in presence of two witnesses.
